RAILROAD-CROSSING.

SPECIFICATION forming part0! Letters Patent No. 367,433, dated August 2, 1887.

Application filed March 2.), 1857. Serial No. 232,918.

To all whom, it may concern.-

Be it known that I, ARTHUR J HOXHAM, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvement in Railroad-Grossings, which invention is fully set forth and illustrated in the following specification and the accompanying drawings.

The object ofthis invention is to construct a railroad-crossing which can be put in place without disturbing the track crossed.

The invention consists of the parts and combinationsof parts hereinafter described and claimed. I

In the accompanying drawings, Figure 1 illustrates in side elevation a side-bearing girderrail crossing a T-rail. Fig. 2 illustrates in plan the parts shown in Fig. 1. Fig. 3 shows a cro'sssection taken at the line h j of Fig. 2. Fig. 4 illustrates in side elevation a side-bearing rail crossing both a center-bearing and a side-bearing girder-rail. Fig. 5 illustrates in plan the parts shown in Fig. 4. Fig. 6 shows in side elevation detached a vertical web for uniting the rails together. Fig. 7 illustrates in plan the crossing complete. Figs. 8 and 9 show details of construction hereinafter particularly described.

In said figures the several parts are inclicated by letters, as follows: A, T-rails forming the main-track rails crossed by the crossing-rails B B, the parts I) b indicating continua tions of said rails B. In Fig. 4 two forms of girder-rail, K L, are shown, instead of a single form of such rail, A A, shown in Fig. 1. The metal web 0 can be either a plain'plate, as is shown in the several figures, or an angle or T bar, or of any other suitable section, should greater rigidity be needed, its essential form being that whatever shape is used should be that of a vertical web to connect with the vertical webs of the crossing-rails. If either crossing-rail has a lower flange, as shown in cross-section, Fig. 3, part of such flange on the left-hand side is cut away, so as to secure a neat side fit of the vertical web of the piece 0. In said figure the lower flange is left on at the righthand side and there serves to support the lifting-chocks D D, by providing each of the same with a lower bearin Should the rail have no lower flange, the necessity of such (No model.)

cutting away of flange is obviated. To the web 0 are attached anglepieces G G, through which pieces are passed the bolts 9 g, which connect the crossing-rail to the rail crossed. Thus the whole connected system is permitted to work, or to come and go together-an important point. The supporting'chairs F F may be of any form to suit the form of rail used, or said chairs may be entirely omitted. The tie-rods E E hold the crossingrails parallel. The exact number and location of said tie-rods can be adapted to suit the circumstances of each case.

If desired, the web of the girder O can be so riveted as to throw the heads of the crossingrails B b b sufliciently above the heads of the crossed rails A or K L, in which case the lifting-chocks D can be dispensed with, for such elevation of the crossing rails permits the flanges of the car-wheels to run upon and over the heads of the rails crossed without jarring the car. The lifting-chocks Dtake the flanges of the wheels on inclined planes and lift the treads of the wheels off the heads of the rails, and thus permit the lifting and crossing to be gradual and without jarring the crossing car. It is preferable, however, to have the heads of the rails upon the same level. In crossing a steanrrailroad track the lifted crossing-rails sometimes become obstructive to the brakebeams of the railroad-cars running on steamroads past the crossing, as said beams lie low down and are apt to be thuseaught. If crossing a streetrailroad, the lifted rails become exposedabove the street-grade, and hence are liable to destructive wear by and to become obstructive to the wheels of street-vehicles.

In place of the angle-piece G, Fig. 9, the part of the web 0 which must be cut away, as shown at S, Fig. 6, to permit of the passage of the through-rail, can be bent over, as shown at G in Fig. 8, and the bolts 9 passed through said part thus bent over. It will thus be seen that the crossing herein shown and described is nonobstructive. It permits of the passing of cars with a minimum of jolting, and its parts are so attached each to the other that the whole system is connected so that said parts can work or come and go together, thus preserving the relative level of the crossingrails, which is. an essential point to be observed, and this is achieved without in any way disturbing the track to be crossed.

In Figs. 1, 4, 5, and 7 the crossing-rails are shown as notched-in to the rails crossed. This notching-in can be easily effected without taking up or disturbing the rails, or can, if desired, be omitted, the only effect'of such omission being to widen the gap to be crossed by the lifted wheels,and thusto somewhat increase the j olting of the cars.

Having thus fully described my said improvements as of my invention, I claim 1. A railroad-crossing consisting of two uncutthronglrrails and two rails divided each into three pieces, said through-rails and said divided rails tied together into one system of crossing-tracks by means of two vertical webpieces or trusses below the rails, substantially as and for the purposes set forth.

2. In combination with the crossing-rails of a railroad-crossing, lifting-ehoeks, as D D, seon red to the webs of the crossing-rails, substan tially as and for the purposes set forth.

In combination with the rails of a railroad-crossing, a girder or web-truss, as C, provided with angle-pieces or offsets, as G, for securing said truss to one set of track-rails of the crossing, substantially as and for the purposes set forth.

4. In combination with the rails of a railroad-crossing, a girder or web-truss, as 0, slot ted near its ends, as at S, to fit over from below the base of the webs of one set of trackrails, substantially as and for the purposes set forth.
